Stockfish based (ThothFishv1.0) Leela-Killer

ThothFishv1.0 described here is an excellent Stockfish modification: http://talkchess.com/forum3/viewtopic.php?f=2&t=70300 You can read there how it can be configured and it is a great Stockfish mod. As I knew that Leela is very strong while many pieces are on the board, and the games are "regular",...

Re: Lc0 wins, but Stockfish is still the best?

This gives Lc0 a huge hardware price advantage. On my testing system. I run a 16 core CPU for $799. At the same time Lc0 plays on a $1500 RTX 2080 ti. Is Lc0 better, yes but Lc0 needs every bit of the 2080 ti. And at almost twice the price to best Stockfish. You can easily find an RTX 2080ti in $12...

Re: Draws with Knight odds are possible against a top GM?

but given the zero for ten result I would imagine that the 2500 player at the 45' + 15" time limit would at least have a fairly competitive match at knight odds. Probably a top GM wouldn't give up more than an occasional draw at that level, but let's see how things stand a year or so from now. Yes,...

Re: program to generare epd file of tactical exercises from pgn

Optimize finding of tactical/interesting positions. 1. Read the pgn backwards or last position first till the start position. Can quickly evaluate position where side to move has the advantage. After saving a max of say 4 interesting positions, you can exit the game and check the next game. pgn fil...

Re: Leela Chess Zero and what is the "Best" Graphics Card.

I dislike the sloppiness of the test and the sweeping conclusions derived from it. "Just completed a test match playing Lc0 Cudnn fp-16 vs Lc0 Cudnn. At blitz time controls. And the results have some implications if more testing confirms the results." I guess either you don't know how to read, or y...

Re: My non-OC RTX 2070 is very fast with Lc0

Maybe after all I will fry the GPU or something :D. My theoretically hardly overclockable GPU is in fact easy to overclock. I installed two additional case fans --- very important --- one larger for GPU and one smaller for CPU case fans, and temperatures on long runs decreased by 12-14 Celsius on bo...

Re: Leela Chess Zero and what is the "Best" Graphics Card.

I dislike the sloppiness of the test and the sweeping conclusions derived from it. In their paper DeepMind indeed showed a bad scaling of A0 (worse than SF8), but on large hardware and going from rapid TC to LTC, not Blitz TC or shorter. And it might be due to not choosing correct MCTS parameters fo...
